Using this hand dryer is easy. Just place your hands in the 6-foot deep drying alcove, and it will dry them in about 17 seconds. Make sure your hands are within the alcove for the best drying performance. When it comes to maintenance, keep the ceramic water-absorbing surface clean to ensure it can effectively capture and evaporate water. Avoid using abrasive cleaners on the stainless - steel body to prevent scratching. If you have any electrical issues, always refer to a professional electrician as this dryer operates on different voltage settings.
